Edge-tool sharpening is one of the most time-consuming tasks in the shop, and one of the most crucial. Good workmanship depends on sharp cutting tools at all stages of a project, yet those tools are vulnerable to many hazards that will dull them prematurely. Contributing editor Roland Johnson finds that a few preventive steps go a long way toward keeping his tools sharp -- cleaning lumber before milling; scrubbing and lubricating cutting blades on bandsaws, tablesaws, and chopsaws; protecting sharp tools such as chisels, drill bits, and router bits from other metal surfaces that will dull them; and doing regular touchups to maintain a tool's edge before its performance suffers.
